Athletes should prioritize foods rich in carbohydrates, proteins, and healthy fats for optimal performance. Carbohydrates serve as the primary fuel source for energy-intensive activities, while proteins are essential for muscle repair and growth. Incorporating nutrient-dense foods such as whole grains, lean meats, fish, fruits, and vegetables provides necessary vitamins and minerals that support overall health. Additionally, hydration plays a vital role, as even mild dehydration can impair performance. Maintaining a balanced diet ensures athletes can perform at their best.
